SPECIFICATION forming part of Letters Patent No. 631,446, dated August 22, 1899.

To @ZZ whom, `it may concern:

Be it known that I, CHARLES W. SMITH, a citizen of the United States, and a resident of Moline, in the county of Rock Island and State of Illinois, have invented certain new and useful Improvements in Compressing-Machines and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to machines for compressing plastic material into cylindrical blocks or eggetes and is designed more especially for compressing artificial fuel consisting of a mixture of coal-dust and heated pitch, although it may be employed for compressing other materials, if desired.

The objectof the invention is to provide an improved construction of the .compressor by which artificial fuel or other material may be compressed into blocks in a rapid and efflcient manner; and it consists in the novel construction and combination of parts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a plan View of a compressor constructed in accordance with my invention. Fig. 2 is a central longitudinal section on the line c Qc,l

Fig. 1. Fig. 3 is a transverse section o n the line y y, Fig. 1. Fig. 4 is a face view of the stationary die at the outer end of the machine. Fig. 5 is a similar view of the longitudinally-movable and rotatable die located at the end of the longitudinally-movable cylinder. Fig. 6 is a detail view showing the crank or arm and pawl which rotate the cylinder. y

In the said drawings the reference-numeral 1 designates a horizontally-movable cylinder having an opening 2 in its upper side, through which the mixture is fed thereto. This cylinder is closed at the outer end by a head 3, and at the other endl is connected therewith a laterally-movable and rotatable .die 4. This die is formed wtrrfour openings 5, extending from end to end thereof, and its outer end is provided with lugs 6, with which engage lugs 6 on a stationary die 7, formed with two diametrically opposite concave or semispherical recesses 8, which form one of the rounded ends of the compressed block, and with two Aopposite peripheral slots Sa, which receive the l compressed blocks as they are expelled from the die 4. Passing through said dies and cylinder-head is a longitudinally-movable but non-rotatable shaft 9, connected with an eccentric-strap l0 of an eccentric 12, secured to a transverse driving-shaft 13. Keyed to this shaftis a hub 14 of a flange or disk 15, to which is secured two opposite inwardly-extending compressi-ng-plungers 16, the inner ends of which are concaved or formed with semicylindrical recesses 17 and two alternately-arranged expellingplungers 18, also formed with concavities 19. These plungers 16 and lSae similar in construction, with the exception that plungers 1S are somewhat longer or extend beyond the plun gers 16 at the inner ends.

r Secured to the driving-shaft 13 is a beveled gear 20, which meshes with a corresponding gear 2l on a rotatable longitudinal shaft 23. This shaft 23 is provided with a wheel 24, fixed thereto, formed with a peripheral camgroove 25,'with which engages a roller 26, journaled to a peripheral stud on the cylinder-head 3, theconstruction and arrangement being such that at the proper time the cylinder 1 and die 4 will be moved away from the stationary die 7, as seen in Fig. 1. The said cylinder is movable longitudinally on the shaft 9, but is non-rotatable, while the die 4 is so connected with the cylinder as to move longitudinally therewith and is also rotatable on said shaft by means hereinafter de- IOO on the cog-wheel 3l.

31, so as to permit it to move laterally or longitudinally with the die without throwing` it out of mesh with said wheel.

Fixed to shaft 23 is an arm or `crank 34, to the outer end ot' which is pivoted a pawl 35, adapted to engage with projections or lugs 3G The other end of this pawl is formed with a projection 37, which engages with a lug 39 on the guide-ring 30 and throws the pawl out of engagement with said lugs. The numeral 3S designates a spring secured to said arm or shaft and engaging with one end of said pawl, so as to throw the latter into engagement with one of the lugs 36 when the pawl passes out of engagement with the guide-ring.

The operation is as follows: The mixture or plast-ic material is fed to the cylinder l through the opening 3 from a mixing-machine or other source of su pply, and the compressor is setin motion, the die4being pushed tightly against the stationary die 7 by the cylinder and cam-wheel, the lugs G engaging with lugs 6 to hold the die 4 against rotation, so that the openings therein shall be in coincidence or alinenient with the recesses and slots, respectively, of the stationary die, as seen in Fig. 2. The plungers 1G and 1S will be now moved forward by the shaft 9, the eccentric, and the driving-shaft, plungers 16 forcing a portion of the material in the cylinder into the openings in the die 4, which are in alinement with the concave recesses in die 7 and compressing it therein. At the same time plungers 1S will force the blocks previously compressed ont of the other openings in said die 4 into the slots in die 7. The plungers will then be withdrawn from the die 4 b y the further movement of thel eccentric. NVhile such movements are taking place shaft 23 is rotating, so that by the time the plun gers are withdrawn from said die the cam wheel and roller will move the cylinder and die 4 away from die 7, so as to disengage the lugs G from lugs 6, as seen in Fig. l. By this time the pawl 35 of the arm or crank 34 will have passed out of engagement with the upper end of the broken guide-ring 30, and the spring 3S will throw the pawl into engagement with one of the projections or lugs 3G, which will rotate the cog-wheel 31, which in turn will correspondingly rotate the cog ring or rim 32, causing die 4 to make a quarter-revolution, so that the openings therein containing the compressed blocks will be brought opposite the slots in the die 5 and the openings from which the compressed blocks have been expelled opposite the concave recesses in die 7. The pawl 35 will now have reached the lug 39 at the lower end of the guide-ring, when the projection 37, engaging therewith, will depress the same, causing its other end to be moved outward and thrown out of engagement with said lug or projection 3G and will not again engage with one of said lugs or projections until it again passes the upper end of the guide-ring 30. When said pawl has passed the said lug 39, the cam-wheel 24 will move the cylinder l and die 4 forward, so that lugs G will engage with lugs C of die 7 and the die 4 be prevented from rotating. The expelling-plungers 18 are so constructed that when they are withdrawn from the die they will barely clear the latter, so that upon their next forward stroke they will not carry any material into the die. The object of reeiprocating the die 4 and cylinder lis to disengage the same from the stationary die 7, so as to allow the die 7 to be rotated.

lVhile I have shown four plungers and four openings in die 4, I do not wish to be limited to this number, as mol'e may be employed if found convenient or desirable.

Having thus fully described my invention, what I claim is* l. In a compressing-machine, the combination with the longitudinally-movable cylinder, the longitudinally-movable and rotatable die having a series of openings extending therethrough and the stationary die formed with alternately-arranged recesses and pe.- ripheral slots, of the alternately-arrauged compressing and expelling plungers of different lengths and means for reciprocating the same, substantially as described.
